This updates car profile handling for Latvian living zones, where living_street should resolve to 20 km/h instead of the generic fallback behavior. It also adds focused cucumber coverage to lock in the country-specific interpretation and updates taginfo metadata accordingly.

• Profile change: Latvia-specific symbolic maxspeed

  • Added lv:living_street = 20 to profiles/car.lua maxspeed_table.
  • Keeps change scoped to symbolic maxspeed resolution only.

• Behavioral coverage: cucumber scenario

  • Added a dedicated scenario in features/car/maxspeed.feature for highway=living_street with maxspeed=LV:living_street.
  • Asserts routed forward/backward speed at 16 km/h +-1 (profile speed reduction applied, with rounding tolerance for short segments).

• Taginfo metadata update

  • Added {"key": "maxspeed", "value": "LV:living_street"} to taginfo.json so the supported symbolic maxspeed value is documented in taginfo output.

-- profiles/car.lua
maxspeed_table = {
  ...
  ["lv:living_street"] = 20,
  ...
}

[!WARNING]

Please add an exception to https://github.com/Project-OSRM/osrm-backend/blob/master/profiles/car.lua#L270 for Latvia for living_street, which is always 20 kmh. I suppose it would be ["lv:living_street"] = 20.

The relevant Latvia Road Law is at point 101. at https://likumi.lv/ta/en/en/id/274865. These always have a living zone entry/exit sign.

Per Latvian tagging guidelines https://wiki.openstreetmap.org/wiki/Lv:Latvian_tagging_guidelines#Mazāki_ceļi, living zones are tagged as living_street and other streets are not.

Thanks.

P.S. I don't know about your specifics of routing penalties, but these should likely be penalized as well for various practical reasons, but that's a separate issue.

P.S.S. I would note that some other countries have living zones too with specific max speeds, especially post-Soviet countries. Someone probably might like to do the same for others.</issue_description>

<agent_instructions>Implement the speed limit for living streets in Latvia as 20kmh as listed in this issue. Verify the implementation by adding a cucumber test. Note that on short segments there can be rounding errors when going from time and distance to speed. Use +-1 as approximation.

if possible verify the tagging rules and the mentions Latvia road law.</agent_instructions>
